Praise God! The replacement part for my PowerBook’s power supply arrived today, just one day after it was ordered. I picked it up this afternoon and the PB is now running great. The battery is fully charged again, and I’ve been spending time getting everything installed and ready.
I almost ran into trouble with OS X. The PB wouldn’t boot from the OS X installer CD, and I was getting scared that the RAM in the computer might not be up to snuff. But it turns out the CD itself was just a little too dirty. So after cleaning it off, everything installed perfectly. Whew, crisis averted.
